NON-BEFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed April 13. 1906. $erial No. 311.463.

To all whom it may concern:

Be it known that I, CONRAD M. CONRAD- soN, a citizen of the United States, residing in the borough of Manhattan, city of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

This invention relates to and has for an object to provide an improved non-refillable bottle, and particularly one wherein the stopper or valve will be carried by a float and will normally be held to its seat by a weight, suitable abutment faces being pro vided for assisting the weight to seat the stopper or valve portion when the bottle is empty and in a tilted position, but not sufficiently tilted for liquid inserted in the attempt to fraudulently refill the bottle to carry the stopper to its seat by floating the same.

In the drawingsaccoinpanying and form ing a part of this specification Figure 1 illustrates a central vertical section of the neck of a bottle embodying a form of my improved construction, the weight, baffle plate and stopper carrying the baffle plate being shown in elevation. Fig. 2 is a plan on the line 22 of Fig. 1 looking from the direction of the arrows; and Fig. 3 is a view of the neck, similar to Fig. 1, showing this in a tilted position.

The bottle is shown as having a neck, designated in a general way by 6, the juncture between the body of the bottle and the neck at about 7 is shown as contracted and affording a valve seat 8 which will cooperate with the face 9 of the stopper float 10 which is shown as elongated and hollow and provided with ribs 11, which will be guided by longitudinally disposed ribs 12 upon the inside of the bottle neck. These as well as the surfaces 8 and 9 may be ground to give them the proper fit. The neck is provided with an enlarged chamber 13 for containing a weight, in the present instance, a sphere 14, such sphere being of suflicient weight and specific gravity that it can overcome the buoyancy of the float 10 in the presence of liquid. The neck of the bottle is shown as continuing at 15 in a reduced portion for forming the mouth of the bottle where a bead 16 having within it an inwardly facing groove which will register with a groove 17 in the closure portion 18 for receiving some suitable sealing material 19. The closure is shown as carrying a baffle plate 20, there being suitable b vpasses for permitting the escape of the liquid through the pouring port 25. The baffle plate 20 is at a suflicient distance beyond the normal lower position of the weight 14 that when the bottle is tilted the weight may go away from the float and permit this to rise from its seat in the pouring of the liquid. Between the chamber 13 and the portion 15 of the neck there is a ridge 21 over which the weight will roll when the bottle is tilted to a certain position, which ridge or abutment will hold the weight from engaging the walls of the chamber 13 and hold it in such. a position that it will press against the top of the float, even when the bottle has been tipped overpast a horizontal position.

It will be seen, particularly by reference to Fig. 3, that the distance between the ridge 21 and the abutment offered by the face of the baffle plate is less than the radius of the weight, consequently when the bottle is tilted to a slightly less position than that shown in Fig. 3 the weight will engage the ridge 21 and the float, even when the float is in a position to rise to its seat in the presence of inwardly passing liquid, and that the weight not only reacts upon with the float below the weight, but also will react in some positions when the float is above the weight. The short distance between the face of the baffle plate and the ridge will permit the weight to over balance for bringing it into its float engaging position. This prevents the arising of any position where neither of the elements will act. This is illustrated by lines 22 and 23 in Fig. 3, 22 indicates the center of gravity of the sphere and how this is beyond the line 23 which runs parallel with the line 22 and intersects the abutment or ridge 21.

After the bottle has been filled and the float 10 and counterweight 14: properly seated the closure member 18 will be placed in the neck of the bottle and sealed therein. The contents of the bottle may be poured ofl when desired by tipping the. bottle; the outrushing liquid carrying the float with the weight outward so that there will be an unobstructed passage for the liquid. The bottle, however, becoming empty an at tempt made to force liquid into it will be met by the float carrying the face 9 against the float when the bottle is tiltedthe face 8, should the bottle be in such a position that the face 8 is above the face 9; if, however, the bottle is in the opposite position the Weight Will cause it to seat.

Having described my invention I claim: In a non-refillable bottle, the combination With a bottle having a neck, a valve seat at the bottle end of the neck, a buoyant valve for seating thereon, the neck of the bottle having means for guiding the valve and a chamber above the normal upper position of the said valve, a spherical Weight in said chamber,- said neck having an integral ridge at the upper portion of said chamber forholding the weight against the valve and away from the Walls of such chamber When the bottle is in certain positions, and an abutment in the neck beyond such ridge and at a distance from the same less than the radius of said spherical Weight 20 and at a sufficient distance from said ridge to permit the Weight to move from the valve When the bottle is in other tilted positions.
